How to insert auto increment?

Hi Expert,
How can I do this without enter 100 time every day?
insert into [tablename] (column1) values(1)
insert into [tablename] (column1) values(2)
....
insert into [tablename] (column1) values(100)
Thank you all for reply-MN

Why do you want to generate 100 rows per day if that's the only column?
Just increment a single value instead. If there are other columns
involved then maybe you can use an IDENTITY column.

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.

|||Hi David,
Thank for reply. Yeah, some day I increate 100 rows, someday 90, or 10...the
value is vary. And there are no other column involved except IDENTITY column.

Don't. There are two good reasons. 1. It's inefficient (because a
single row will do the same thing). 2. It may be unreliable (an
IDENTITY sequence can have gaps so the maximum value doesn't
necessarily match the number of rows).
Instead, use a single row:
CREATE TABLE tbl (x INTEGER PRIMARY KEY DEFAULT (1) CHECK (x=1) /*
single row constraint */, col1 INTEGER NOT NULL);
INSERT INTO tbl (col1) VALUES (0);
GO
Then keep updating it like this:
UPDATE tbl SET col1 = col1 + 100 ;
In case you do find it useful again, you can populate a table with
default values only or an IDENTITY column only using the DEFAULT VALUES
clause:
INSERT INTO tbl DEFAULT VALUES;

Hi MN,
I'd very much like to know why you need to do that....
But the asnwer is: make a permanent table of numbers in your database
(see http://www.aspfaq.com/show.asp?id=2516), and use that:
INSERT INTO tablename (column1)
SELECT Numbers.Number
FROM dbo.Numbers
WHERE Numbers.Number BETWEEN 1 AND 100
